| Abstract |
|
To evaluate the postoperative prognostic factors of pars plana vitrectomy for the proliferative diabetic retinopathy, the authors studied retrospectively the surgical results of 65 eyes that have been followed over 6 months postoperatively. The surgical results were varied according to the indication. Seventy six percent of eyes with vitreous hemorrhage obtained final vision of 5/200 or better. Similar results were obtained in 73% of eyes with macular traction detachment, 47% of eyes with rhegmatogenous-traction detachment. Rhegmatogenous-traction detachment has less favorable outcome than vitreous hemorrhage and macular traction detachment. Factors associated with a favorable visual prognosis were as follows: (1) preoperative visual acuity of 5/200 or better, (2) the avoidance of performing lensectomy, (3) the avoidance of using intraocular gas bubbles, (4) the absence of preoperative retinal detachment. Thirteen eyes resulted in anatomic failure ; vitreous hemorrhage was the cause of failure in 4 eyes(31%) and anterior hyaloid fibrovascular proliferation in 3 eyes(23%), The causes of poor visual outcome included optic atrophy in 3 eyes, ischemic maculopathy in 2 eyes, submacular fibrosis in 1 eye and cataract in 1 eye. |
